Patent DE-3015838-A1 (DE)
Title: Tapered location for rollers - is installed between piston and brake pad and produces axial pull to increase brake force
Inventor: STOKA ROBERTO
IPC: F16D65/097
Filed: 1980-04-24
Abstract: The disc brake assembly is operated by a hydraulic cylinder (25). Two cylindrical rollers (26) are located between the outside of the brake pad mounting plate (37) and the piston (12). The two rollers (26) are located by a pair of ring plates (11,29) so that they point towards the brake disc (16) centre. The circular drag from the brake disc moves the roller location plates slightly in a relative angular direction. Thus the angled (alpha) location faces (21) produce an axial pull that increases the braking force.

Title: Height adjustable curtain hung clinker wall underpinning - has positioning fish-plate joining screw for hinged bracket support to wall
Inventor: MODERSOHN WILHELM
IPC: E04F13/08
Filed: 1980-11-20

Patent DE-3113325-A1 (DE)
Title: High-voltage switching chamber
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/70
Filed: 1981-03-30
Abstract: Especially in the case of SF6 circuit breakers according to the method for cooling the switching-off arc in a double-nozzle gas flow having a pressure gradient which is produced during the switching-off itself, one of the main problems is to overcome the restrictive coupling between the predominantly gas-dynamic requirements for the nozzle configuration in the thermal phase of current interruption and the dielectric requirements in the switching phase when there is no current, without having to accept disadvantageous side effects at the same time. Reducing the duration of the arc and simplifying the operation and design represent further urgent problems. In order to solve these problems, a nozzle consisting of electrically conductive material and a nozzle consisting of insulating material are arranged at an axial distance apart. The switching-element system is split into two subsystems. The subsystem for carrying the continuous current is located outside the compression space. The compression cylinder, which is manufactured from insulating material, is used as a contact support. The subsystem for carrying the arc current is accommodated in the internal region of the nozzles. The current is transferred from one switching-element system to the other using the parallel-commutation method. The movable components of the switching-element systems are mechanically and electrically connected to one another. They are jointly driven by the compression cylinder. The drive elements do not prevent the switching gases flowing out. In order to reduce the electrical field intensity in the region of the switching paths, the movable arc and continuous-current switching elements are supplemented to form an electrode which has a large area in terms of its effect on the formation of the field.

Patent DE-3119865-A1 (DE)
Title: Aerodynamically completely controllable hang glider
Inventor: TUERK RUDOLF DR
IPC: B64C31/028
Filed: 1981-05-19
Abstract: In an aerodynamically completely controllable hang glider two hanging control sticks which are arranged to the side with respect to one another and can be operated independently of one another are provided which are connected by means of a cable pull, guide rollers and levers in each case to the tail unit and to the associated nearer aileron of the lifting surface in such a way that given parallel deflection of the two control sticks about the pitch axis the elevator of the tail unit is operated, given opposite deflection about the pitch axis the rudder of the tail unit is operated, and given deflection respectively of one control stick about the roll axis the associated aileron is operated. The control sticks can be reached in like manner with essentially the same forearm hold both by a pilot in the footstart position hanging in a locked holding arrangement, and by a pilot in the essentially horizontal lockable flight position. It is possible to change from one position to the other. This results in the provision of a reliable, simply designed complete control of a hang glider, in which a maximum of control functions can be attained with a minimum of operational control members. In particular, no control functions are triggered by the feet of a pilot, so that in the critical phase of starting or landing there is the possibility of fully controlling and correcting the apparatus. A particular advantage of the invention is the independent control of the two ailerons. In a particularly preferred embodiment, the flying vehicle of a hang glider is constructed to a delta design with swivellable outer wing tips, the rear tail unit being a collapsible unit which is connected via a two-dimensional joint to the body of the flight vehicle.

Title: Method for marking telecommunications cable wires
Inventor: KATZSCHNER WOLFGANG DR PHIL
IPC: H01B13/34
Filed: 1981-05-25
Abstract: The invention relates to a method for marking telecommunications cable wires, coloured fusion adhesive (17) being used as the marking means. This fusion adhesive (17) is placed in the fluid state in a container (19) and is deposited, as markers (23), on the cable wires (22) to be marked via porous pressure stamps (3) on the circumference of rotating wheels (1, 2). As a result of the use of fusion adhesive (17), it is now possible (in contrast to the situation with previous methods) not to apply the marking until shortly before the processing to form cables, for example shortly before stranding (twisting). <IMAGE>

Abstract: The invention provides a method and a device for the use of alcohol fuel as fuel for a petrol-driven internal combustion engine. The alcohol (A) and the petrol (G) are each separately vaporised and carburetted from separate tanks (2 and 3) and mixed with air, fed to the plenum chamber (P) of the internal combustion engine (E), in which they are combined with the air with which they are mixed before being fed to the respective combustion chamber of the internal combustion engine (E).

The petrol (G) is fed conventionally by way of a carburettor (C) to the plenum chamber (P), whilst the alcohol (A) is fed by way of a vaporiser (20). In the vaporiser (20) the alcohol (A) is vaporised by means of hot air (H), which is drawn from the positive crankcase ventilation (PCV), further heated by heat exchange with the exhaust gases and introduced into the vaporiser (20) by means of an air feed nozzle (23) the direction of whose jet lies transversely, preferably perpendicular to the jet direction of an alcohol feed nozzle (22), the outlet for the alcohol-air mixture (A/H) preferably being located in the extended jet direction of the air feed nozzle (23). <IMAGE>
